Abstract
An ink jet printing apparatus and method for forming images by selectively actuating a multiple number of ink chambers. An amount of energy U0, which is determined by U0=Ui−Ud, is applied to each non-ejecting chamber, wherein Ui is the energy imparted to each ejecting chamber and Ud is the energy that is carried away by a single droplet of ink, when all the nozzles are driven to eject ink at a maximum ejection ratio, with the temperature rise of ink jet head being saturated.
